16. @gaqzi How  to  make  a  reusable  app? Easiest way to start is to use cookiecutter. ! ! ! ! $ pip install cookiecutter $ cookiecutter git@github.com:pydanny/ cookiecutter-djangopackage.git !
17. @gaqzi starting  an  app  with  cookiecutter
18. @gaqzi TravisCI  /    Continuous  Integration Travis can handle multiple versions of Python/Django for you as long as none of the packages differ. ! Meaning that if you only care about support 2.7, 3.3 you can use a Travis matrix to test your app. Which gives you nice output like this one.
19. @gaqzi Coveralls  /  Test  coverage
20. @gaqzi tox  /  Multi  version  testing Define which versions of Python you want to test with and which package versions on that given version. ! For instance to test Python 2.6 with Django 1.4, 1.5 and 1.6. Python 2.7 on Django 1.4, 1.5, 1.6 and 1.7 Python 3.3 on Django 1.6 and 1.7 ! Checkout tox-matrix for an easy way to define versions and dependencies.
